you could probably blame it on the timezone... or, if you went fast enough, you could maintain that while three days have passed for us it is still only sunday for you.. maybe in London you met Madonna who took you for a ride in her 37 foot mini-cooper limo (manual windows) and convinced you to turn to the kabbalah so weren't allowed make any tribute on sunday.. maybe you adopted the polish calendar.. or your travels set you free and you decided there and then to make up the days of the week as you go along. (you got bored after 'floozeday' and decided a more traditionally named day could possibly be permitted once every 'ooble' days). Or maybe your brief encounter with Halen taught you the mystic power of 'sod off you cunt' and you don't need to explain your reasons anymore...
